"Professor, what is the Triwizard Tournament?" Muya asked in confusion.
The doll shook her head. "Professor, I don't know either."
Snape: ...Did you remember what you came here to do?
"Dumbledore already explained it on the first day of term. Miss Muya, were you daydreaming at the time?"
"Professor, Moody was staring at me so intensely that I didn't listen properly."
Snape gave a light cough. "Perhaps Dumbledore would be interested in telling you again."
He sat down and pointed at the mountain of potion ingredients piled beside them. "You may leave once you've finished processing those."
Both Muya and the doll saw the corner of Snape's mouth lift by a single pixel. They exchanged a look, wondering whether he had wanted them in detention to help him work all along.
Still, it was nothing much. Muya had already grown used to processing potion ingredients.
When they left, the doll cast an Invisibility Charm on herself and followed behind Muya.
They spoke in low voices. "Could that guy be a masochist?" The doll blurted out something outrageous, startling Muya so badly that she nearly tripped on flat ground.
"What happened? Tell me everything." As expected, gossip was human instinct.
Though Muya couldn't see it, the doll still spread her hands helplessly. "Didn't I hit him with a Cruciatus Curse?"
Muya nodded.
"That guy actually started laughing quietly on the floor." The doll rubbed her arms. "Eugh, it was seriously creepy."
Muya frowned and rubbed her arms as well.
Good grief, he really was a pervert.
"Hey, Ya Ya, we developed a new product."
"For the upcoming Triwizard Tournament."
The two of them grinned and said in unison, "And 1,000 Galleons!"
Oh, so that last part was the real point.
"What is it?"
Muya was rather curious.
"Ta-da, Aging Potion." George
